Common configuration parameters
When you define a common parameter for a specific sensor you make it unique for your fishing scenario and needs.
Description
Gear monitoring sensors are delivered from Kongsberg Discovery readily set up with common default settings. In some cases, you may find that the default parameters do not suit your operational needs.

The configuration parameters may vary from one sensor to another. Not all configuration parameters are available for all sensors.
Details
Read Sensor
You may prefer to check first the existing configuration of the selected sensor. Select Read Sensor so that the sensor can “send” its information to the computer. Prior to read the sensor’s data, the communication between the computer and the sensor must have been established.
Select Receiver
Select the receiver to be used to receive the specific sensor data. The type or receiver you select here must be the same interfacing the current gear monitoring sensor. Otherwise, the communication between sensor and receiver will not be established.
Select Location
The gear illustration corresponds to the one you chose in Select Gear in the Installation dialog box. It shows the possible locations of the selected sensor. The capital letter indicates where you can place the selected sensor. The selection you make here may affect the measurements offered by the sensor. Click in the illustration to specify where the current sensor shall be located. If you program a sensor for one function (or measurement) in one location, it will not work if you install it somewhere else.
Direction
In order to do a proper configuration of the sensor, you must select if the sensor is going to point to the vessel or to the gear.
Measurement
You can select the measurements you want your sensor to make. The available options will vary according to the gear system you are working with, the location you have chosen for the sensor and where it points to. Once you have selected your measurement, the relevant additional required parameters are automatically shown.
Note
The number of measurements a PX sensor can make is determined by the sensor type. The maximum number of measurements a sensor can make is 8.
Offset
This parameter will help you focus on the part of the trawl that is most important for you. You can manually enter an offset value. The offset value must be based on the physical locations of the sensors and the properties of the gear. The Offset values for a measurement can also be entered in the Offsets dialog box.
Blanking zone
When the sensor is set up to measure height from the middle of a trawl door, the physical properties of the door can cause false echoes and hence wrong height information. You can insert a “blank space” to inhibit false detections as the sensor will disregard all echoes received from objects inside the defined zone. A typical blanking zone is 1.5 metres from the sensor to the bottom of the trawl door.
Remote code
Remote code is only available for Geometry and Spread measurements, and when you set up a Remote sensor for any of these measurements. You can select the channel used to handle the communication between the “master” and the “remote” sensors.
Channel
All sensors are provided by Kongsberg Discovery with predefined communication channels. The predefined communication channel will always be shown as the default channel. It may be required to change one or more communication channels, and there may be many reasons for this.
•  You have more than one of each sensor. For example, if you have three temperature sensors, they MUST communicate on three different channels.
•  Other vessels near yours use the same gear monitoring system (or similar) and they have one or more of their sensors set up to the same communication channels as you have. This will create interference as you will “read” other sensors.
Update Interval
This value specifies at what time interval the update is to be done. A faster update rate gives you information more often, but will decrease the battery life.
Output Power
If you work in shallow and/or confined waters you may find it useful to reduce the output power to avoid reverberation. A high output power may also provide added range capacity. The higher the power output, the lower the battery capacity.
Label
By default, the TV80 will assign a name (label) to every sensor depending on its location and the measurements it will make. The name (label) you give to the sensor will appear in the Sensor List.
Body Serial Number
Type in the serial number you will find on the body of your sensor. This number will help you quickly identify the sensor should you need assistance.
Program Sensor
Once you have defined the settings and measurements, select Program Sensor to apply them to the sensor you are configuring. Once the sensor has been programmed, the TV80 will automatically read the new sensor parameters back from the sensor to verify that they have all been set correctly.
